Clark, Pottstown, Pa, assignorto Refractory 8; Insulation fiorporation, New York, N.Y., a corporationof Delaware Filed Dec. 18, 1962, Ser. No. 245,6h6 2 Claims. (Cl. 275-15)This invention relates to a gun for distributing wet solid mixes, suchas mixes containing finely divided refractory compounds, for example. Anobject of this invention is to provide an apparatus which can besuspended in a closed space such as a refractory lined furnace forexample, and which has the ability to distribute wet particulate mixesof the type above referred to, to all exposed surfaces within thefurnace with rapidity and uniformity. Other objects and advantages ofthis invention will further become apparent hereinafter.

Referring to the drawing,

FIG. 1 is a view in side elevation, partly in section, showing aspecific form of gun constructed in accordance with this invention.

FIG. 2 is an enlarged perspective view showing details of thedistributing apparatus at the base of the gun.

FIG. 3 is a view similar to FIG. 1 showing the bottom portion of amodified form of gun in accordance with this invention, and

FIG. 4 is an enlarged perspective view somewhat like that of FIG. 2,showing the modified form of the distributing apparatus at the base ofthe gun which appears in FIG. 3.

Referring now to the specific forms of the invention selected forillustration in the drawings, the number designates a generallycylindrical container mounted on frames 11, comprising a container forthe wet mix of solid material. At the upper end of the container 10,mounted on the frames 11, is an air motor 12 receiving pressurized airthrough a pipe 13 and connected by a train of gears generally designated14 to an inner shaft 15 and an outer drive tube 16 both of which extendalong the elongated axis of the container 10.

Outer tube 16 is drivingly connected to an agitator or mixer element 17located just above the bottom of the container, which maintainsuniformity of the wet mixture in the location just above the center andbottom portion of the container 10.

Just below the mixer 17, the container 10 is provided with an opening 29constituting an outlet for the wet solids. Just below the outlet opening20 is a distributor generally designated 21, the details of which areshown more clearly in FIG. 2. As will be seen, the distributor 21 isdriven by the inner shaft 15 from the motor 12, and comprises aplurality of curved rib members 22 all of which are mounted on a commonbase plate 23. The ribbed plate formed at the members 22 and 23 catchesand supports the wet solid material which is discharged through theopening 20 and throws such material radially outwardly utilizingcentrifugal force, thus distributing the material throughout theenclosure, such as a refractory furnace or the like, in which theapparatus is contained.

ice

It will be observed that the apparatus shown in FIGS. 1 and 2 throws thematerial throughout a 360 spread.

The apparatus shown in FIGS. 3 and 4 is specially constructed to limitthe angular scope of coverage of the throw. In accordance with FIGS. 3and 4, the ribbed plate 23 and the ribs 22 are surrounded by a generallycylindrical guard 24 having an opening 25 therein. As shown, the openingis a generally rectangular portion of the cylinder 24, and it will beseen that as the blades 22 rotate the cylinder 24 serves as a guard,thus focusing or limiting the throw of material to that of the open area25.

It will be seen that, with the independent drive of the impeller 17relative ot the blades 22, and with the provision of facility forcontrolling the speeds thereof, the wet mix of solid particles can befed downwardly through the opening 20 at a controlled rate and can bedistributed uniformly throughout virtually any enclosure into which themixing equipment according to this invention can be introduced.

While this invention has been described with reference to one embodimentthereof, it will be apparent to those skilled in the art that variouschanges other than those referred to above may be made in the form ofthe device, that equivalent elements may be substituted for thoseillustrated in the drawings, that parts may be reversed, and thatcertain features of the invention may be used to advantage independentlyof the use of other features, all within the spirit of the invention asdefined in the appended claims.

It is claimed:

1. A gun for distributing wet solid mixes containing finely dividedparticles to the wall of a refractory lined furnace and the like, saidgun comprising a suspendable cylindrical container for the mix; a shaftmounted for rotation on the vertical axis of said container andprotruding through the bottom thereof; a centrifugal distributor afiixedto the lower end of said shaft below said container, said distributorcomprising a circular plate having curved radial ribs on the uppersurface thereof; a hollow cylindrical sleeve mounted for rotation on thevertical axis of said container and surrounding said shaft; an impellerin the lower portion of said container affixed to said sleeve; motordrive means for driving said shaft and said sleeve independently; and adischarge opening in the bottom of said container for discharging mix tosaid distributor.

2. A gun as claimed in claim 1 characterized in that said distributor isprovided with a peripheral wall having a discharge opening therein forcontrolling the area of distribution of said mix.
